摘　　要：研究了己二酸二辛酯(DOA)、聚酯增塑剂与粉末丁腈橡胶(P83)高分子改性剂对软质聚氯乙烯(PVC)材料的低温脆化温度、分子迁移率和空气热失重等性能的影响。结果表明,DOA可改善软质PVC材料的耐低温性能,但却降低了材料的耐久性能;聚酯增塑剂则正好相反;P83则可以同时显著提高材料的耐低温性和耐久性。The influences of dioctyl adipate (DOA),polyester plasticizer and powder (acrylonitrile-)butadiene rubber (P83)modifier on brittle temperature,molecular mobility ratio and weight loss in the air of the soft PVC composite were studied.The result showed that DOA could improve the low temperature resistance of soft PVC,but decrease its durability;polyester plasticizer had the opposite effects on (properties) of composite;P83 could increase simultaneously its low temperature resistance and durability greatly.
